So If I dont want to waste money on Nav, there is no point in the avic? No other features I would be missing out on? I heard the avic interface is way better. Is there any other HU I should look at?
Hey, I have a Z with stock nav already, so I dont really need the nav function. I was looking at the 4000 and it seems to be the same as the d3, minus nav. Is this true? How do they compare, quality/interface wise?
